Objective To understand the awareness status of nutrition and health knowledge among adult residents in Chongqing from 2021 to 2023,and to provide scientific evidence for optimizing nutrition health education content and formu-lating precise intervention strategies.Methods In 2021-2022 and 2022-2023,using a multi-stage sampling method,13,758 and 16,281 people from all districts and counties of Chongqing were selected as survey participants,respectively.A questionnaire survey was conducted using the Nutrition and Health Knowledge Questionnaire for Chinese Adult Residents Aged 18-64 Years.Based on the questions and answers in the questionnaire,71 knowledge points were summarized,and the correct rate for each knowledge point was calculated.Results In the 2021-2022 survey,the score of the Nutrition and Health Knowledge Questionnaire among participants was(59.50±13.01)points;in the 2022-2023 survey,the score was(66.63±11.68)points.In both surveys,the differences in Nutrition and Health Knowledge Questionnaire scores among participants of different genders,ages,educational levels,and work units were statistically significant(P<0.05).Regres-sion analysis showed that gender,educational level,and work unit were influencing factors for the awareness rate of nutri-tion and health knowledge among survey participants from 2021 to 2023(P<0.05).The correct rates for each knowledge point among participants ranged from 1.2%to 89.7%(2021-2022)and 4.1%to 92.4%(2022-2023).Among these,categories with a correct rate of less than 25%in either survey included 5 knowledge points:"recommendations for soy and product intake","recommendations for sugar intake","dietary recommendations for food diversity","estimation of com-mon food weights",and"recommendations for nutritious breakfast and lunch combinations"in the Chinese Dietary Guide-lines.Categories with a correct rate of 25%to<50%in either survey included 23 knowledge points.Categories with a low-er correct rate of 50%to<75%and those with a correct rate≥75%in both surveys included 30 and 13 knowledge points,respectively.In addition,there were 43 common knowledge points covered in both the 2021-2022 and 2022-2023 surveys,among which the differences in correct rates for 40 knowledge points between the two surveys were statistically significant(P<0.05).Conclusion The level of nutrition and health knowledge among adult residents in Chongqing urgently warrants im-provement.Precise health education should be carried out targeting weak knowledge points and key populations(such as males,middle-aged and elderly people,and those with low education levels)to comprehensively enhance residents'nutrition and health lit-eracy.
